i’m not very inclined to add this plugin to the maintenance burden for every discourse update & rebuild. discourse is already extremely javascript-heavy, and adding graphviz to the runtime reqs adds to that load, on both server- and client-side. in all my tests, graphviz is fairly stressful to run, with an instant ~30% cpu spike.
on the post entry side: users have to type dozens of error-free lines of graphviz code to e.g. describe a modular synth patch, but it’s much easier to simply post a patch pic from modulargrid.
